What is the point of "cd ." in "cd . && npm install"?

Question

I'm using express generator. After running the generator it outputs the following:

   install dependencies:
     $ cd . && npm install

What is the point of cd .?

Answer 1

It means that you ran this:

$ express

(or possibly express .)

In other words, you told express-generator to create a project in the current working directory. Alternatively, you could have provided a subdirectory name:

$ express foo

In that case, the commandline it generates makes a bit more sense:

install dependencies:
  $ cd foo && npm install
